Regitration form + PayPal payment form

I need a registration form to be created on my website. In addition, I need to process payments using PayPal on the same page or after the regitration form. The process must be automated. Just like Get a Freelancer site has it. Person wants to make a payment and the website redirects to PayPal page with our account information. And when the person is done, the page goes back to our website.

Our webiste is hosted with [url removed, login to view] and we built the website using GoDaddy's Website Tonight service. I hope it will not be a problem for you. We would agree if you want to copy the website and create it outside of the Website Tonight service, but we would need to have a backoffice(system admin) in order to make changes(add pictures, edit text, etc) ourselfs. PM me for more details on the website and fields I need to be on my registration form. Thanks
